Nokia Flexi WCDMA BTS tackles site related costs
How much can you save?
OPEX • Power • Site rent • Remote capacity provisioning CAPEX • Site implementation • Site construction • Transmission
• Antenna system • Power system
Nokia Flexi WCDMA BTS Improved BTS Site CAPEX and IMPEX Shelter / equipment room can be avoided by outdoor BTS installation. Modular, small and light BTS minimizes also required civil work cost Antenna line civil work and component cost can be minimized by locating BTS close to the antennas (maximizes also cell capacity) In indoor installations additional air conditioning is not needed due to low power consumption

Nokia Siemens Networks Flexi WCDMA BTS Installation
Objectives After the completion of this chapter, the participant will be able to:
• Examine a Nokia Siemens Flexi WCDMA BTS for correct installation
Work Order Handling the modules and unpacking the
delivery Preparing the modules for installation Installing the stand-alone BTS on the floor Fixing adapter mechanics to plinth
Mounting the stand-alone BTS on the wall Mounting the stand-alone BTS on the pole Installing modules inside Nokia cabinet Installing optional modules Installing transmission sub-module Grounding the BTS Connecting external power feed
Handling the Modules and unpacking delivery When handling the modules, always use the antistatic wrist strap as shown in the Connecting the antistatic wrist strap figure below. The cabinet must be grounded, otherwise the antistatic wrist strap will not work. Refer to Grounding the BTS section.
ESD ANTI-STATIC WRIST STRAPS SHOULD BE WORN WHEN HANDLING ANY UNIT WHICH DISPLAYS THE ESD LOGO
Handling the Modules and unpacking delivery
After mounting the Plinth, attach the site ground.
Unpack and check the delivery System Module Front and Rear covers External Cable Entry System Module

Supported Configurations
Clearances
Anchoring the plinth on the floor Without maintenance Space
With maintenance Space
Recommended installation order
Check that the plinth is installed correctly.
Actual stacking configuration may vary
Installing modules on the floor
Installation example: modules on the floor
Fixing adapter mechanics to plinth
Adapter mechanics brackets are installed on the plinth in wall and pole installations
Mounting the stand-alone BTS on the wall
A plinth is required for mounting the modules on a wall Check that the plinth adapter mechanics are installed as instructed in Fixing adapter mechanics to plinth section.
Mounting a second plinth on the wall
Mounting the modules on a wall
One mounting plinth per two modules is installed on a wall. Refer to Mounting the plinth on a wall for plinth installation instructions.
Mounting the stand-alone BTS on the pole
NOTE: There are different lengths of bolts and places for bolts in the bracket.
Mounting the plinth on a pole
Recommended module installation order
• Do not install more than two modules per plinth • The modules must be installed with front panels facing left or right. Do not install modules so that the front panels face up or down.
Mounting the modules on the wall or pole 1 Tip Line up the locating marks in the module to help aligning the holes with fixing studs.
4 Tip Use the markings in the module to help aligning the holes with fixing studs.

Installing optional modules Flexi power module (FPMA) consists of connector blocks and four slots for AC/ DC sub-module (FPAA) or battery sub-module (FPBA).
FPMA can include:
. two FPAAs and two FPBAs . three FPAAs and one FPBA . one FPAA and three FPBAs . one FPAA and three free slots for expansion.
Grounding the BTS
When modules are installed inside a cabinet, separate module grounding is not required.
If the BTS has more than one plinth (for example in wall or pole installations), connect the main ground to one of the plinths and ground all the modules to that plinth.
